If your diamond sets﻿ off a standard Geiger Counter I don’t﻿ think I would wear it. Yes they radiate diamonds and the gold is always looking for mercury and cyanide even atmospheric quantities so they are both poisoning you﻿ the more you wear them.

Lets say that the radiation level in space was comparably to the radiation output from my cathode ray tube, the simple unit here produced over a volt, and the surface area is minor compared to the same out put solar﻿ cell. So in space it may provide a cost efficient alternative to solar cells.
